Mitt Romney said Sunday that GOP presidential candidate Ted Cruz winning two primary states this weekend proves the Texas senator can stop front-runner Donald Trump, but declined to rule out his own White House scenario.

Romney, a former Massachusetts governor and the Republicans' 2012 presidential nominee, repeated remarks from last week, telling “Fox News Sunday” that he wouldn’t launch an eleventh-hour campaign for president. But he declined to reject being “drafted” at the GOP convention in July to be the party’s general election candidate.
